postProcessImperativeFunctionResult

protected O postProcessImperativeFunctionResult(I rawInputs,
                                                Object functionInputs,
                                                Object functionResult,
                                                SimpleFunctionRegistry.FunctionInvocationWrapper function,
                                                com.microsoft.azure.functions.ExecutionContext executionContext)

Post-processes the result from a non-reactive function invocation before returning it to the Azure runtime. The default behavior is to possibly convert the result.

Provides a hook for custom function invokers to extend/modify the function results handling.

Parameters:

rawInputs - the inputs passed in from the Azure runtime

functionInputs - the actual inputs used for the function invocation; may be different from the rawInputs

functionResult - the result from the function invocation

function - the invoked function

executionContext - the Azure execution context

Returns:

the possibly modified function results

postProcessReactiveFunctionResult

protected O postProcessReactiveFunctionResult(I rawInputs,
                                              Object functionInputs,
                                              org.reactivestreams.Publisher<?> functionResult,
                                              SimpleFunctionRegistry.FunctionInvocationWrapper function,
                                              com.microsoft.azure.functions.ExecutionContext executionContext)

Post-processes the result from a reactive function invocation before returning it to the Azure runtime. The default behavior is to delegate to postProcessMonoFunctionResult(I, java.lang.Object, reactor.core.publisher.Mono<?>, org.springframework.cloud.function.context.catalog.SimpleFunctionRegistry.FunctionInvocationWrapper, com.microsoft.azure.functions.ExecutionContext) or postProcessFluxFunctionResult(I, java.lang.Object, reactor.core.publisher.Flux<?>, org.springframework.cloud.function.context.catalog.SimpleFunctionRegistry.FunctionInvocationWrapper, com.microsoft.azure.functions.ExecutionContext) based on the result type.

Provides a hook for custom function invokers to extend/modify the function results handling.

Parameters:

rawInputs - the inputs passed in from the Azure runtime

functionInputs - the actual inputs used for the function invocation; may be different from the rawInputs

functionResult - the result from the function invocation

function - the invoked function

executionContext - the Azure execution context

Returns:

the possibly modified function results

postProcessMonoFunctionResult

protected O postProcessMonoFunctionResult(I rawInputs,
                                          Object functionInputs,
                                          reactor.core.publisher.Mono<?> functionResult,
                                          SimpleFunctionRegistry.FunctionInvocationWrapper function,
                                          com.microsoft.azure.functions.ExecutionContext executionContext)

Post-processes the Mono result from a reactive function invocation before returning it to the Azure runtime. The default behavior is to Mono.blockOptional() and possibly convert the result.

Provides a hook for custom function invokers to extend/modify the function results handling.

Parameters:

rawInputs - the inputs passed in from the Azure runtime

functionInputs - the actual inputs used for the function invocation; may be different from the rawInputs

functionResult - the Mono result from the function invocation

function - the invoked function

executionContext - the Azure execution context

Returns:

the possibly modified function results

postProcessFluxFunctionResult

protected O postProcessFluxFunctionResult(I rawInputs,
                                          Object functionInputs,
                                          reactor.core.publisher.Flux<?> functionResult,
                                          SimpleFunctionRegistry.FunctionInvocationWrapper function,
                                          com.microsoft.azure.functions.ExecutionContext executionContext)

Post-processes the Flux result from a reactive function invocation before returning it to the Azure runtime. The default behavior is to block and possibly convert the results.

Provides a hook for custom function invokers to extend/modify the function results handling.

Parameters:

rawInputs - the inputs passed in from the Azure runtime

functionInputs - the actual inputs used for the function invocation; may be different from the rawInputs

functionResult - the Mono result from the function invocation

function - the invoked function

executionContext - the Azure execution context

Returns:

the possibly modified function results
